“If you’re a dude not feeling your best”
Visited on June 5, 2025
If you’re a dude not feeling your best, at any age, Mike should be in your care network. Endlessly knowledgeable, and is willing to treat to make you feel better. He’s also not ashamed to push you to find another specialist. On this appointment, my thyroid antibodies were jacked up. He prescribed hormone to make me feel better, gave me clear instructions on fitness and nutrition, and directed me to find a specialist to rule out thyroid cancer. Serious: if you’re a man above the age of 30, you need Mike to order you labs and evaluate you.
Example: my good buddy followed my advice and saw Mike. Ran a full workup. Mike didn’t push treatment he didn’t need, he only recommend supplements that he could take to optimize his levels. Mike will very much treat aggressively if you need it, but isn’t a pill pusher—he’s an optimizer, and does what’s right for each patient. I’ve referred all my male friends to Mike, and there is a stark difference between the friends that follow his wisdom and those that don’t.
In terms of bedside manner, Mike is no bullshit and to the point. He’s a wealth of knowledge. I wouldn’t go to any other provider.
One of my friends was worried that Mike was ‘only a PA’, but honestly this is what you want. Hormone optimization is literally Mike’s bread and butter, it’s all he really does. You could see Dr Saya, sure, but unless you have other complications, you really need to go to Mike.
I would not be the man I am today without Mike Linkous. Listen to what he says, follow his intuition, order every lab. You’re in the best f$%&ing hands on the planet.

“Beth was awesome as always”
Visited on June 5, 2025
Beth was awesome as always. She addressed my concerns making adjustments to dosage as needed. It was obvious that she reviewed my labs and knew my concerns ahead of time of call. I like that she bases her care not only on my lab results but how I actually feel. Patient portal is most helpful as I can easily and timely order the things that Beth ordered for me.
